Description

Technology Field

[0001] The present invention relates to a flow-type evaporator, an ice-making device including the same, and a water purification device. The invention is configured such that heat is evenly transferred to a plate member where ice is formed during de-icing, allowing the ice to be easily separated without the use of separate de-icing water, thereby minimizing the degree of ice melting during de-icing. Furthermore, the invention is configured such that the de-icing water circulates only to the outside of a pair of plate members, thereby preventing a decrease in the cleanliness of the de-icing water. Background Technology

[0002] Generally, flow-through evaporators are used in devices that generate ice by flowing ice-making water over the surface of the evaporator, and then de-icing the generated ice from the evaporator to provide it to the user. Such flow-through evaporators can be used in various devices that require ice generation, such as ice-making devices or water purification devices.

[0003] Korean Registered Patent Publication No. 10-1335953 of Daeyoung E&B Co., Ltd. discloses a conventional ice maker. This ice maker is equipped with an evaporator through which a low-temperature refrigerant flows, an ice-making plate vertically positioned to contact the evaporator, a water tank positioned below the ice-making plate for storing water (ice-making water and de-icing water) falling from the ice-making plate, and an ice storage tank provided on the outside of the water tank for storing falling ice. Additionally, the ice-making plate is equipped with partitioning sections that divide each section to generate a plurality of ice in a horizontal direction. When water flows through this ice-making plate, ice is generated in the part in contact with the evaporator, and in particular, the generated ice is formed while attached not only to the ice-making plate but also to the partitioning sections. Therefore, for de-icing, it is necessary to quickly separate all parts to which ice is attached. High-temperature gas is supplied to the evaporator to separate the parts attached to the ice-making plate, and de-icing water is flowed into the inner part of the partition, that is, the part where the evaporator is located, to separate the parts attached to the partition. If de-icing water is not used, the parts attached to the partition will not separate quickly, and as the ice size becomes very small due to the high-temperature gas supplied to the evaporator, there may be a problem of reduced user satisfaction; thus, the use of de-icing water is unavoidable. However, as this de-icing water is configured to pass through the outer surface of the copper-tube evaporator and collect in a tank to circulate together with the ice-making water, there is a problem of reduced cleanliness of the generated ice.

[0004] The ice-making unit disclosed in Japanese Patent Publication No. 2009-264729 of HOSHIZAKI ELECTRIC CO LTD is equipped with an ice-making plate having a plurality of protrusions extending in the vertical direction installed at predetermined intervals in the horizontal direction, and an evaporator tube arranged on the back side of the ice-making plate and extending in the horizontal direction. When ice-making water flows through the ice-making plate, ice is formed on the part in contact with the evaporator tube, and the ice formed in this way adheres to the ice-making plate and the protrusions. When a de-icing operation to separate the ice begins, a high-temperature gas valve is opened to circulate high-temperature gas to the evaporator tube, and a water supply valve is also opened to supply de-icing water to the back side of the ice-making plate, thereby heating the ice-making plate and separating the ice. However, even in this case, the problem of reduced cleanliness of the generated ice still exists because the de-icing water is configured to pass through the outer surface of an evaporator made of copper tubing and then collect in a water tank to circulate together with the ice-making water.

[0059] FIG. 3 is a perspective view of a water-flow type evaporator according to one embodiment of the present invention, FIG. 4 is an enlarged view of part A of FIG. 3, FIG. 5 is a perspective view showing a state in which one side plate member of the water-flow type evaporator according to one embodiment of the present invention has been removed, and FIG. 6 is an enlarged view of part B of FIG. 5.

[0060] As illustrated in FIGS. 3 to 6, a water-flow evaporator according to one embodiment of the present invention may include a pair of plate members (100) arranged facing each other, a pipe member (200) arranged between the pair of plate members (100) through which a low-temperature refrigerant or a high-temperature gas flows, and a heat transfer member (300) that is in thermal contact with the pipe member (200). An ice-generating surface (110) in which ice (C) is generated is formed on the outer side of the pair of plate members (100), and a heat transfer surface (120) in which it is in thermal contact with the pipe member (200) is formed on the inner side of the pair of plate members (100). At this time, the outer side of the pair of plate members (100) refers to the part where ice (C) is generated as ice-making water (W1) flows, and the inner side of the pair of plate members (100) refers to the part in which it is in thermal contact with the pipe member (200). This ice-making water (W1) contains purified water (W3) that has been filtered while passing through the filtration section (10'). On this ice-making surface (110), a partition wall (111) extending in a direction intersecting the pipe member (200) is formed to protrude outwardly from a pair of plate members (100) to partition the area (K) where ice (C) is generated. That is, the ice-making water (W1) supplied to the flow-type evaporator (20) flows along the outer side of a pair of plate members (100) while distributed by the partition wall (111), and ice (C) is generated in the part that is in thermal contact with the pipe member (200).

[0061] As illustrated in FIG. 4, the first surface (C1) of the ice (C) being produced is formed attached to the ice production surface (110), and the second surface (C2) extending from the first surface (C1) is formed attached to the outer surface of the partition wall (111). That is, as the ice-making water (W1) flows, ice (C) is first produced on the ice production surface (110), and at this time, the first surface (C1) of the ice (C) is attached to the ice production surface (110). In this state, as the ice-making water (W1) continues to flow, the size of the ice (C) increases, and ice is also formed on the outer surface of the partition wall (111), and at this time, the second surface (C2) of the ice (C) is attached to the outer surface of the partition wall (111). Therefore, in order to remove ice, it is necessary to quickly separate the first surface (C1) and the second surface (C2) of the ice (C). To this end, when high-temperature gas is supplied to the interior of the pipe member (200), the heat supplied through the pipe member (200) is transferred to the ice (C) through the heat transfer surface (120) and the ice generation surface (110), thereby separating the first surface (C1) from the ice generation surface (110). At the same time, the heat supplied through the pipe member (200) is transferred to the partition wall (111) through the heat transfer member (300), thereby separating the second surface (C2) from the partition wall (111). To this end, the heat transfer member (300) can be inserted and positioned on the inner surface of the partition wall (111). That is, the ice (C) is formed on a plate member (100) and heat is transferred evenly during de-icing, so that the ice (C) can be easily separated without using separate de-icing water, thereby minimizing the degree of ice melting during de-icing. Additionally, since the ice-making water (W1) is configured to flow only to the outside of a pair of plate members (100), it is possible to effectively prevent the cleanliness of the ice (C) as well as the circulating ice-making water (W1) from deteriorating.

[0062] Figure 7 is a cross-sectional view of section I-I of Figure 3.

[0063] As illustrated in FIG. 7, in a water-type evaporator according to an embodiment of the present invention, the heat transfer member (300) may be provided with a first transfer surface (310) that is in thermal contact with a pipe member (200) and a second transfer surface (320) that extends from the first transfer surface (310) and transfers heat to a partition wall (111) by conduction. The first transfer surface (310) is in direct surface contact with the pipe member (200). That is, when high-temperature gas is supplied to the inside of the pipe member (200) for de-icing, heat is transferred to the first transfer surface (310) that is in thermal contact with it, and subsequently, as heat is transferred to the partition wall (111) through the second transfer surface (320) by conduction, the second surface (C2) of the ice (C) partially melts and separates from the partition wall (111). In this way, heat transferred from the pipe member (200) through the first transfer surface (310) is directly transferred to the second transfer surface (320) and the partition wall (111) by conduction, thereby enabling rapid heat transfer so that the ice can be easily separated and the ice (C) can maintain its size and shape, thus improving user satisfaction.

[0064] Additionally, as illustrated in FIG. 7, in a water-type evaporator according to an embodiment of the present invention, the partition wall (111) may be provided with an opposing wall (111a) that is in thermal contact with a second transfer surface (320) and a supporting wall (111b) that connects both ends of the opposing wall (111a). That is, the first surface (C1) of the ice (C) being produced is formed attached to the ice production surface (110), and the second surface (C2) extending from the first surface (C1) is formed attached to the outer surface of the partition wall (111), that is, the outer surface of the opposing wall (111a). In this state, when high-temperature gas is supplied to the inside of the pipe member (200) for de-icing, heat is sequentially transferred (conducted) through the first transfer surface (310) and the second transfer surface (320) as described above, and subsequently, as heat is transferred to the opposing wall (111a) through the second transfer surface (320) via conduction, the second surface (C2) of the ice (C) partially melts and separates from the outer surface of the opposing wall (111a). In this way, as the heat transferred from the pipe member (200) through the first transfer surface (310) is directly transferred to the second transfer surface (320) and the opposing wall (111a) via conduction, rapid heat transfer becomes possible, allowing the ice to be easily separated and the ice (C) to maintain its size and shape, thereby improving user satisfaction. In addition, since the distance between opposing walls (111a) can be maintained at a constant level by providing a supporting wall (111b), structural stability can be secured even when used for a long time.

[0065] FIG. 8 is a cross-sectional view illustrating a partition wall of a water-type evaporator according to another embodiment of the present invention.

[0066] As illustrated in FIG. 8, in a water-type evaporator according to an embodiment of the present invention, a pair of opposing walls (111a) are arranged facing each other, and the inner surface of the opposing walls (111a) is formed with an incline (θ) such that the distance between the inner surface of the pair of opposing walls (111a) is increased. For example, when the distance between opposing walls (111a) formed in the part adjacent to the inner side of a pair of plate members (100) is called the inner distance (di), and the distance between opposing walls (111a) formed in the part adjacent to a support wall (111b) is called the outer distance (do), the incline (θ) is formed on the inner surface of the opposing walls (111a) such that the inner distance (di) is increased more than the outer distance (do). The inner surface of the opposing wall (111a) is formed with an incline (θ) so that the spacing between the inner surfaces of the pair of opposing walls (111a) increases, thereby improving manufacturability by allowing the mold frame to be easily removed when forming the plate member (100) using a mold or the like.

[0067] Figure 9 is a cross-sectional view of section II-II of Figure 3.

[0068] As illustrated in FIG. 9, in a water-flow evaporator according to an embodiment of the present invention, a contact surface (210) that is in direct surface contact with a heat transfer surface (120) may be formed on the pipe member (200). In this way, when the pipe member (200) through which a low-temperature refrigerant or a high-temperature gas flows comes into surface contact with the heat transfer surface (120) formed on the plate member (100), rapid heat transfer becomes possible, so that ice (C) can be formed quickly during ice making and can be easily separated during ice removal, thereby improving user satisfaction.

[0069] As illustrated in FIG. 7, in a water-flow evaporator according to an embodiment of the present invention, a mutually bondable bonding surface (130) may be formed on the perimeter of a pair of plate members (100) that are arranged facing each other. As described above, since the water-flow evaporator (20) according to an embodiment of the present invention does not use de-icing water even during de-icing, the interior of the pair of plate members (100) is sealed through the bonding surface (130), thereby preventing air or de-icing water from entering and thus preventing a decrease in the cleanliness of the de-icing water.

[0070] As illustrated in FIG. 7, in a water-type evaporator according to an embodiment of the present invention, a folded surface (140) that is folded inward is formed on the perimeter of a pair of plate members (100) that are arranged facing each other, and the aforementioned joining surface (130) may be formed extending from the end of the folded surface (140). When a folded surface (140) is formed on each of the pair of plate members (100) in this way, it becomes easy to secure an internal space where a pipe member (200) can be placed, thereby improving ease of manufacturing.

[0071] As illustrated in FIG. 3, the fluid-type evaporator according to an embodiment of the present invention may further include a connector member (400) communicating with the pipe member (200) so that a low-temperature refrigerant or a high-temperature gas is supplied to the interior of the pipe member (200). At this time, as illustrated in FIG. 4, a seating surface (150) on which the connector member (400) is seated may be formed around the perimeter of the plate member (100). That is, in order to supply a low-temperature refrigerant or a high-temperature gas to the pipe member (200), it is necessary to connect the pipe member (200) with a heat transfer fluid supply unit (30) provided externally, and the heat transfer fluid supply unit (30) and the pipe member (200) are connected so that they communicate with each other through the aforementioned connector member (400). With one end of the connector member (400) connected to the pipe member (200), the other end of the connector member (400) is positioned outside the plate member (100), so that the other end of the connector member (400) can be exposed to the outside even after the perimeter of the plate member (100) is joined, and a heat transfer fluid supply unit (30) is connected to the other end of the connector member (400). In addition, a seating surface (150) on which the connector member (400) is seated is formed on the plate member (100), so that the connector member (400) can be fixed in the correct position, thereby ensuring structural stability.

[0072] As illustrated in FIG. 5, in a flow-type evaporator according to an embodiment of the present invention, a partition wall (111) is formed to extend parallel to the direction in which the ice-making water (W1) flows, and a plurality of partition walls (111) are spaced apart at a certain interval (L). A pipe member (200) is formed to extend in a direction intersecting the plurality of partition walls (111), and a plurality of pipe members (200) can be spaced apart at a certain interval (M) along the direction in which the ice-making water (W1) flows. In this way, when a plurality of partition walls (111) are formed to extend parallel to the direction in which the ice-making water (W1) flows and a plurality of pipe members (200) are also formed to extend in a mutually spaced state in a direction intersecting the partition walls (111), multiple ice (C) can be produced simultaneously, thereby improving user convenience.

[0073] FIG. 10 is a plan view illustrating a pipe member according to another embodiment of the present invention.

[0074] As illustrated in FIG. 10, a flow-through evaporator according to another embodiment of the present invention may further include a first connecting member (500) that connects a plurality of mutually adjacent pipe members (200) so that a low-temperature refrigerant or a high-temperature gas flowing through one pipe member (200) moves sequentially (series connection) to another pipe member (200) arranged adjacently. By connecting the pipe members (200) in series in this way, there is no need to consider the flow rate distribution of the low-temperature refrigerant or the high-temperature gas, thereby making the design of the flow-through evaporator easier. At this time, the pipe member (200) may be formed in an S-shape that curves along the direction in which the ice-making water (W1) flows. To achieve this, the straight and curved portions of the pipe member (200) may be formed separately and configured by connecting them integrally during the manufacturing of the pipe member (200). By configuring it in this way, the straight and curved parts of the pipe member (200) can be simply connected, and since deformation to form an S-shape is not required, the pipe member (200) can be formed in an accurate shape. Alternatively, it is also possible to configure it by extending the pipe member (200) as a single unit and deforming it by applying an external force to the pipe member (200). By configuring it in this way, there is no need to connect the pipe members (200) to each other, making rapid manufacturing possible.

[0075] FIG. 11 is a plan view illustrating a pipe member according to another embodiment of the present invention.

[0076] As illustrated in FIG. 11, a water-flow evaporator according to another embodiment of the present invention may further include a second connecting member (600) that connects the ends of a plurality of pipe members (200) so that a low-temperature refrigerant or a high-temperature gas is supplied (parallel-connected) to a plurality of pipe members (200) simultaneously. When the pipe members (200) are connected in parallel in this way, the low-temperature refrigerant or the high-temperature gas is supplied to all pipe members (200) simultaneously, thereby enabling rapid ice making or ice removal. At this time, it is necessary to distribute the flow rate so that the low-temperature refrigerant or the high-temperature gas is supplied evenly to each pipe member (200).

[0077] FIG. 12 is a perspective view showing a state in which one side plate member of a water-flow type evaporator according to another embodiment of the present invention has been removed, FIG. 13 (a) is a cross-sectional view of the section III-III of FIG. 12, and (b) is a cross-sectional view of the section VI-VI of FIG. 12.

[0078] As illustrated in FIG. 12, in a water-type evaporator according to another embodiment of the present invention, the plate member (100) is formed from a plurality of plate sheets (101) of different materials, wherein a heat transfer surface (120) is formed on the plate sheet (101) each disposed on the inner side of a pair of plate members (100), and an ice generation surface (110) is formed on the plate sheet (101) each disposed on the outer side of a pair of plate members (100). For example, the first sheet (101a), which is the plate sheet (101) on which the heat transfer surface (120) is formed, is made of copper (Cu) material to allow for smooth heat transfer, and the second sheet (101b), which is the plate sheet (101) on which the ice generation surface (110) is formed, is made of stainless steel (SUS) material considering the cleanliness of the ice-making water (W1) or ice (C). By configuring it in this way, smooth heat transfer and cleanliness can be secured simultaneously. Such a plate member (100) can be manufactured by compressing and attaching a first sheet (101a) and a second sheet (101b) to each other during the process of manufacturing the material of the plate member (100).

[0079] In a water-type evaporator according to another embodiment of the present invention, the heat transfer member (300) may be a plate sheet (101) disposed inside a partition wall (111). That is, as described above, the plate member (100) is formed from a plurality of plate sheets (101) of different materials, wherein a heat transfer surface (120) is formed on the plate sheet (101) disposed on the inside and an ice generation surface (110) is formed on the plate sheet (101) disposed on the outside, and by disposing of the plate sheet (101) with the heat transfer surface (120) inside the partition wall (111), heat supplied through high-temperature gas is transferred to the partition wall (111) through the plate sheet (101) without using separate de-icing water, thereby enabling rapid heat transfer and improving user satisfaction by allowing ice to be easily separated.

[0080] As previously described, this type of water-type evaporator (20) used in an ice-making device may include a pair of plate members (100) positioned opposite each other, a pipe member (200) positioned between the pair of plate members (100) through which a low-temperature refrigerant or a high-temperature gas flows, and a heat transfer member (300) in thermal contact with the pipe member (200). An ice-generating surface (110) where ice (C) is generated is formed on the outer side of the pair of plate members (100), and a heat transfer surface (120) in thermal contact with the pipe member (200) is formed on the inner side of the pair of plate members (100). On the ice-generating surface (110), a partition wall (111) extending in a direction intersecting the pipe member (200) is formed protruding outward from the pair of plate members (100) to partition the area (K) where ice (C) is generated. The first surface (C1) of the ice (C) being generated is formed attached to the ice generation surface (110), and the second surface (C2) extending from the first surface (C1) is formed attached to the outer surface of the partition wall (111). At this time, in order to de-icing, it is necessary to quickly separate the first surface (C1) and the second surface (C2) of the ice (C). When high-temperature gas is supplied to the inside of the pipe member (200), the heat supplied through the pipe member (200) is transferred to the ice (C) through the heat transfer surface (120) and the ice generation surface (110), and the first surface (C1) is separated from the ice generation surface (110). In addition, at the same time, heat supplied through the pipe member (200) is transferred to the partition wall (111) through the heat transfer member (300) so that the second surface (C2) is separated from the partition wall (111), and for this purpose, the heat transfer member (300) can be inserted and placed on the inner surface of the partition wall (111).That is, the ice (C) is formed on a plate member (100) and heat is transferred evenly during de-icing, so that the ice (C) can be easily separated without using separate de-icing water, thereby minimizing the degree of ice melting during de-icing. Additionally, since the ice-making water (W1) is configured to flow only to the outside of a pair of plate members (100), it is possible to effectively prevent the cleanliness of the ice (C) as well as the circulating ice-making water (W1) from deteriorating.

[0081] At this time, in an ice-making device including a water-type evaporator according to an embodiment of the present invention, a mutually bondable bonding surface (130) may be formed on the perimeter of a pair of plate members (100) arranged facing each other. That is, since the ice-making water is not used even during ice removal, the interior of the pair of plate members (100) is sealed through the bonding surface (130), so that air or ice-making water (W1) does not flow in, thereby preventing a decrease in the cleanliness of the ice-making water (W1).

[0082] In addition, in an ice-making device including a water-type evaporator according to an embodiment of the present invention, a folded surface (140) that is folded inward is formed on the perimeter of a pair of plate members (100) that are arranged facing each other, and the aforementioned joining surface (130) may be formed extending from the end of the folded surface (140). When a folded surface (140) is formed on each of the pair of plate members (100) in this manner, it becomes easy to secure an internal space where a pipe member (200) can be placed, thereby improving ease of manufacturing.

[0083] In an embodiment of the present invention, a plurality of heat transfer members (300) may be spaced apart at regular intervals along the height direction (Z). Each of these heat transfer members (300) may be positioned to match the height at which the pipe member (200) is positioned. That is, since the heat transfer member (300) is not positioned in a location where the pipe member (200) is not positioned, even if a low-temperature refrigerant flows inside the pipe member (200), it is possible to prevent the formation of ice (C) on the outer surface of the partition wall (111) in the part where the heat transfer member (300) is not positioned. Therefore, this prevents the continuous growth of ice (C) along the outer surface of the partition wall (111) in the height direction (Z), thereby allowing the ice (C) to be easily separated during de-icing. In addition, since the heat transfer member (300) is positioned only for a predetermined length from the part that contacts the pipe member (200), compared to the case where the heat transfer member (300) is integrally extended along the height direction (Z), heat can be intensively transferred for a short period of time during de-icing, thereby reducing power consumption, and since heat is not released to the outside in the part where the heat transfer member (300) is not positioned, the time required for de-icing can be shortened.

[0084] Meanwhile, as previously described, the water-type evaporator (20) used in the water purification device may also include a pair of plate members (100) arranged facing each other, a pipe member (200) arranged between the pair of plate members (100) through which a low-temperature refrigerant or a high-temperature gas flows, and a heat transfer member (300) that is in thermal contact with the pipe member (200). An ice-generating surface (110) where ice (C) is generated is formed on the outer side of the pair of plate members (100), and a heat transfer surface (120) that is in thermal contact with the pipe member (200) is formed on the inner side of the pair of plate members (100). On the ice-generating surface (110), a partition wall (111) extending in a direction intersecting the pipe member (200) is formed protruding outward from the pair of plate members (100) to partition the area (K) where ice (C) is generated. The first surface (C1) of the ice (C) being generated is formed attached to the ice generation surface (110), and the second surface (C2) extending from the first surface (C1) is formed attached to the outer surface of the partition wall (111). At this time, in order to de-icing, it is necessary to quickly separate the first surface (C1) and the second surface (C2) of the ice (C). When high-temperature gas is supplied to the inside of the pipe member (200), the heat supplied through the pipe member (200) is transferred to the ice (C) through the heat transfer surface (120) and the ice generation surface (110), and the first surface (C1) is separated from the ice generation surface (110). In addition, at the same time, heat supplied through the pipe member (200) is transferred to the partition wall (111) through the heat transfer member (300) so that the second surface (C2) is separated from the partition wall (111), and for this purpose, the heat transfer member (300) can be inserted and placed on the inner surface of the partition wall (111).That is, the ice (C) is formed on a plate member (100) and heat is transferred evenly during de-icing, so that the ice (C) can be easily separated without using separate de-icing water, thereby minimizing the degree of ice melting during de-icing. Additionally, since the ice-making water (W1) is configured to flow only to the outside of a pair of plate members (100), it is possible to effectively prevent the cleanliness of the ice (C) as well as the circulating ice-making water (W1) from deteriorating.

[0085] At this time, in a water purification device including a water-flow type evaporator according to an embodiment of the present invention, a mutually bondable bonding surface (130) may be formed on the perimeter of a pair of plate members (100) arranged facing each other. That is, since the de-icing water is not used even during de-icing, the interior of the pair of plate members (100) is sealed through the bonding surface (130), so that air or de-icing water (W1) does not flow in, thereby preventing a decrease in the cleanliness of the de-icing water (W1).

[0086] In addition, in a water purification device including a water-flow type evaporator according to an embodiment of the present invention, a folded surface (140) that is folded inward is formed on the perimeter of a pair of plate members (100) that are arranged facing each other, and the aforementioned joining surface (130) may be formed extending from the end of the folded surface (140). When a folded surface (140) is formed on each of the pair of plate members (100) in this manner, it becomes easy to secure an internal space where a pipe member (200) can be placed, thereby improving ease of manufacturing.

[0087] As described above, the ice (C) can be easily separated without using separate ice-making water by configuring heat to be evenly transferred to the plate member (100) where ice is generated during ice-making, thereby minimizing the degree of melting of the ice (C) during ice-making, and by configuring the ice-making water (W1) to circulate only to the outside of the pair of plate members (100), the cleanliness of the ice-making water (W1) can be prevented from deteriorating.

Those skilled in the art who understand the spirit of the present invention may easily propose other embodiments within the scope of the same spirit by adding, changing, deleting, or adding components, and such are also to be considered to fall within the scope of the spirit of the present invention.
